All, With the release of the cygwin 1.3.3 dll, the '//x' method of referencing drives no longer functions. We were using that in the makefiles, so I've changed it to use '/cygdrive/x' which seems to be the proper way. Not sure how this will affect builds on other systems. We definitely need to move to a new build system as described by Miguel in another thread. HTH, Nick D.
